Whacky weather with high and low temperatures.

Two days of warm followed by cold…
This will wreak havoc with fish health.

Those rearing rainbow trout will need to harvest their fish today, if their water temperature approaches 23 degrees Celsius or higher. They are cold water fish and can’t tolerate high temperatures.

Those with outdoor ponds will need to improve water quality conditions and add vitamin C to their water to help boost their fish immunity. The fluctuations in temperature is stressful for fish. On Tuesday, consider adding salt to the pond at a rate of 2g/L.

Those with axolotls need to invest in a chiller for summer, putting them in the refrigerator (set 8 degrees Celsius) as a temporary measure.

Yours sincerely,
